Benefits of technology

The patent describes a method and device for estimating the breathing rate of a person based on their physiological signals. The method involves extracting a waveform from the signals and counting how many waves there are, which represents the drift of the signal over time. By measuring this drift, the person's breathing rate can be accurately determined without needing to analyze the signal using complex calculations. This technology can be used in clinical settings to help monitor a person's breathing.

Problems solved by technology

However, in the previously mentioned technique, the electrodes are necessary, and wearing the electrodes brings inconvenience to the person during the respiratory rate measurement.
Other techniques, such as the Electrocardiography Derived (ECG-Derived) Respiration and Photoplethysmography Derived (PPG-Derived) Respiration, have been proposed for measuring the respiratory rate, but those techniques rely upon calculating peaks of the ECG signals and the PPG signals, which leads to heavy computation.
Further, for the person having lower heart rate, ECG-Derived Respiration and PPG-Derived Respiration cannot determine the respiratory rate precisely.
Therefore, how to provide a convenient and precise method for estimating the respiratory rate without heavy computation is an issue for relevant researchers to work on.

Embodiment Construction

[0015]Reference will now be made in detail to the present preferred embodiments of the disclosure, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.

[0016]The baseline drift is a common phenomenon that could be normally seen in physiological signals measured from an examinee, especially in an electrocardiography (ECG) signal and a photoplethysmography (PPG) signal. In addition, baseline drift is usually caused by low frequency interference happened during the measurement of the physiological signals, such as human breathing. Usually, the baseline drift is regarded as noise in the physiological signals, so it is mostly eliminated or reduced from the physiological signals. However, in the present application, taking advantage of the baseline drift, a respiratory rate of an examinee may be estimated precisely without heavy computation.

Abstract

A method of estimating a respiratory rate and an electronic apparatus are provided. The method includes following steps. A physiological signal is obtained. A wave signal associated with baseline drift is extracted from the physiological signal. A wave number of the wave signal is counted, and the respiratory rate is estimated according to the wave number.

Description

BACKGROUNDTechnical Field[0001]The present disclosure relates to an estimation method and an electronic apparatus thereof, and more particularly relates to a method of estimating respiratory rate and an electronic apparatus thereof.Description of Related Art[0002]As medical technology improves every day, countless lives have been saved and the overall quality of life continues to improve over time. Especially, development of medical devices and equipment has made significant contribution to the improvement of the medical technology. Nowadays, many wearable devices and monitor systems have been applied in continuously measuring vital signs of a person. Through the measured vital signs, physical health condition of the person could be assessed.[0003]Respiratory rate is one of the vital signs widely used as an early and sensitive indicator of deterioration and serious illness. A common technique applied in the respiratory rate measurement involves measuring transthoracic impedance thro...
